Jason and List,

 

Thanks for sharing. I like craters. Here you may see a really small Franconia iron with nice craters that the finder was so kind to let me have:

  Hello All,

  After a bit of work on his part, and no fewer than thirty-seven emails that did or didn't get to wherever they were supposed to go (we may never know what gets lost within the bowels of the internet...), Jeff Kuyken was able to get a number of pics of cratered Sikhotes up onto his site.

  They're of seven Sikhote-Alins in our collection (viz., my father's and my collection), which display pits on leading edges, trailing edges, non-oriented irons, and in a fairly wide range of sizes.
  Enjoy!

  7.9g
  Oriented.
  Crater on trailing edge.
  Diameter of crater is 3mm with a depth of ~1.5mm.
  Upraised rim, and small bump visible in the bottom of the pit itself.

  54.6g
  Not oriented.
  Crater is approximately 2.5mm across and about 2mm deep.
  Upraised rim.

  Not oriented.
  Crater has a 2mm diameter and a 1/2mm depth.

  And here's a picture of all of the Sikhotes together; the order from left to right, back row to front.

  6, 5, 4,
